Throttle delay/ hesitation ‘23 limited

[Dewey]

Mine was fine for a long time. Seemed it learned my driving habits and adjusted accordingly. I usually drive pretty hard so it seemed the throttle programming recognized that.
Last week I towed my boat for about 800 miles and after disconnecting I notice a drastic change in throttle response. The delay is very obvious. While towing I was very easy on the throttle the entire time. Only thing I can figure is it adjusted for that and has to relearn again.
Such a stupid system. My 4th Gens were never like this. Hit the gas and instant power. Don’t understand how they could screw that up so bad.

Interesting. I did just tow a trailer about 1700 miles a couple weeks ago. My memory is a little fuzzy on if it was happening before then. I think it was, but I'm definitely not sure. I also did just have the brake controller installed before that trip.

I've got the same issues, except mine started from zero k's. I run a '23 sport GT. A bit annoying, i've got 20,000 k on it.

You've got a GT, kit put it into manual shifting and shift up/down. Will probably solve 99% of your issue

I’m kinda used to the surge but googling it, sounds like it’s a redesign from the 22s and newer.
the other issue, its Not happening when the engine is shut down. Rolling into a stop sign, stopping (slowing ) and then accelerating to get out into traffic Is when the hesitation or lack of response happens.

This is exactly what I experience with my 2023.

I had the same 2021 but without etorque and it didn’t do this.

I can’t believe how much more I like my 2021 over this 2023 due to this issue alone.

Is there a fix for this?

Hi All, I was wondering if anyone was making any progress with this before I head back to the dealer. I have a 22' 5.7 Laramie that I purchased used in January with 50K miles. The most noticeable throttle delay is when I am slowing to a stop and then try to re accelerate. The delay could be a full second and a half before the truck actually goes. Last night I was slowing to make a left hand turn and then went to reaccelerate and nothing. I thought I was going to get T boned with my kids in the car.

That's not throttle delay, that's the transmission hunting for the right gear. As you are slowing down, it's not downshifting to conserve fuel, when you don't come to a complete stop and try to accelerate again, then the transmission has to try and downshift to the correct gear to match the throttle input and speed. But since the throttle input is changing so fast it can't react fast enough. You can try manually downshifting with the gear limit switches as you slow down and you will find that hesitation all but goes away

The surge forward is from ET, and is a totally separate from auto stop start. The ET motor generator turn the wheels 1/2 turn when the brake is released to save fuel.

That’s not accurate. ET assists in the first 1/2 turn once you press the throttle, it doesn’t turn the tires on its own.
Assists being the key word there.

So it doesn’t creep forward when you let the brake go?

Or try tow mode

HSKR - I drove around for a good 45min and used the gear limited like you suggested. Every time I approached a turn, I limited down the gear to 2 and felt the transmission downshift. Unfortunately, when I reapplied the throttle the delay was still there. It just feels like a dead pedal for that second.

Thanks for the response, I kinda figured the surge is an etourqe thing, not a big fan of it.
i thought about the pedal monster but man, I shouldn’t have to do that. I pull out in traffic, feel the delayed response and ending up mashing it to get it moving so I don’t get whacked. Ill keep mentioning it to the dealer but the response delay shouldn’t be this long, even for stock.

Yup, my 23 does the same thing and it's horrible. I don't even enjoy driving the truck because of that. You explained it to a T. There's literally nothing and then all of a sudden, BAM way too much. The drivability is trash. I notice it even more when I'm driving through the neighborhood with multiple stop signs in a row, that's when it gets really annoying because when you hit the gas after a stop, theres nothing and then the truck tries to catch up and makes it uncomfortable as **** when it catches up to where it should have been from the stop

Must be an e-torque programming issue

Tow mode changes how it drives. Kinda feels like sport mode

Of course it does… so does any other car/truck with start stop that doesn’t have eTorque when the engine starts back up and you’re letting off brake pressure.

Right. IIRC, it was assist during the first 1/2 turn, not the first 1/2 turn when accelerator is pressed. I wish I knew where I saw that .

curious as to what you can find. Anything I can read/view says ”helps” with acceleration and taking off. I can’t find anything that says it does it all on its own.
That being said… it’s half a turn…But it is like 130 lb ft of torque..
If you find anything that states it helps propel forward without any input on the accelerator, I’ll firmly stand corrected sir.

 

[Snekpete]

Some things to try:

1) Turn off Auto Start Stop
2) Calibrate the Throttle Body
3) Try a new Throttle Body ~ $200

I did some searching, but haven't found anything concrete to support my claim. So I may be incorrect.
